Description

Technical Field

[0001] This invention belongs to the field of CNC machine tool technology, specifically relating to a five-axis CNC machine tool with equidistant cutting function. Background Technology

[0002] Five-axis CNC machine tools add two rotary axes to the traditional three-axis design, and all five axes can move in a coordinated manner at the same time, so that the tool always maintains the optimal cutting posture and position relative to the workpiece. When cutting semi-finished products or raw materials, they have the characteristics of fast cutting speed and small kerf.

[0003] Patent publication number CN211277072U discloses a five-axis CNC machine tool with equidistant cutting function, including a five-axis CNC machine tool body, a limiting block, and a light-shielding plate. A support arm is mounted on top of the machine tool body, and a Z-axis slide body is provided on the outer wall of the support arm. A vertical axis rotating block is mounted on the bottom of the Z-axis slide body. A horizontal axis passes through the interior of the vertical axis rotating block, and a laser cutting head body is provided on the side of the horizontal axis. A mounting ring is mounted on the side of the Z-axis slide body, and a slot is formed on the outer wall of the mounting ring. A locking block is installed inside the slot, and a mounting plate is provided on the outer side of the locking block. This patent features a single-pass equidistant cutting function to improve the work efficiency of batch cutting production, and has a good light-shielding protective device to prevent laser scattering from damaging the eyesight and skin of workers.

[0004] The aforementioned device also has the following problems: While it improves the efficiency of batch cutting production by performing single equidistant cuts, when cutting thinner materials, if the two ends of the material are clamped for positioning, the center may bend due to the resistance force, causing the laser cutting point to deviate from the predetermined position, thus reducing the cutting accuracy. At the same time, it is difficult to support the center of the bottom of the thin plate. When the thin plate is wide, the center may deform downward due to gravity. Furthermore, during the cutting process, it is difficult to create sufficient space for the air jet mechanism to cool the cutting debris, which may increase the possibility of secondary adhesion between the debris and the thin plate. Summary of the Invention

[0005] The purpose of this invention is to provide a five-axis CNC machine tool with equidistant cutting function to solve the problem mentioned in the background art that when cutting thin materials, if the two ends of the material are clamped for limitation, the center position is easily bent and deformed due to the resistance force, which causes the laser cutting point to deviate from the predetermined position, thereby reducing the cutting accuracy.

[0006] To achieve the above objectives, the present invention provides a five-axis CNC machine tool with equidistant cutting function, comprising: a base, two support mechanisms symmetrically arranged around the base, a sliding mechanism on the top of the support mechanism, a drive mechanism slidably mounted on the left side of the sliding mechanism, and a cutting mechanism at the bottom of the output end of the drive mechanism. When an electric slide rail is activated, it drives a sliding plate to move towards the cutting mechanism, causing the thin plate to move synchronously. Furthermore, when the cutting mechanism performs laser cutting on the thin plate, the drive mechanism and the sliding mechanism operate synchronously, enabling multi-axis motion. The thin sheet is equidistantly displaced and cut using a drive mechanism and electric slide rails. Two electric slide rails are symmetrically and fixedly installed on the outer sidewall of the base. A sliding plate is slidably installed inside each electric slide rail. An electric push rod is fixedly installed on the side of the sliding plate away from the base, and the electric push rod is telescopic. A U-shaped plate is fixedly installed at the telescopic end of the electric push rod. During the process of horizontally placing the thin sheet material into the U-shaped plate from left to right, the bottom of the thin sheet contacts the circumferential surface of the guide roller inside the bottom end of the U-shaped plate. The thin sheet causes the guide roller to rotate due to friction, thereby separating the thin sheet from the U-shaped plate. Sliding friction is converted into rolling friction. Then, the electric push rod, limited by the sliding plate, is activated. The telescopic end of the electric push rod pushes the U-shaped plate towards the center of the base. At this time, the U-shaped plate increases the bearing area of ​​the thin plate. An anti-denting device is provided below the U-shaped plate to support the thin plate. Around the anti-denting device, an anti-adhesion device is provided to prevent cutting debris from adhering. Several guide rollers are equidistantly and rotatably installed inside the square groove of the U-shaped plate. Roller plates are slidably installed on the inner sidewall of the U-shaped plate via springs. A ladder is slidably installed on the bottom of the inner wall of the U-shaped plate via springs. The frame has a vertical plate fixedly installed on the top of the roller plate and a U-shaped telescopic plate fixedly installed on the top of the sliding plate. When thin plates of different thicknesses come into contact with the circumferential surface of the guide roller, their tops will contact and push the circumferential surface of the roller inside the roller plate, causing the roller plate to slide upward along the inner side wall of the U-shaped plate. At this time, the roller plate adaptively fits the top edge of the thin plate of different thicknesses, and when the roller plate rises, it releases the restriction on the inclined surface of the trapezoidal frame. The trapezoidal frame abuts against the side wall of the thin plate through the spring force. The thicker the thin plate, the more the roller plate rises and the greater the displacement force of the trapezoidal frame, and vice versa.

[0007] According to another advantageous design of the present invention, the driving mechanism is a multi-axis driving device, the cutting mechanism is laser cutting, the telescopic end of the electric push rod moves through the interior of the sliding plate, the bottom of the U-shaped plate is provided with a square groove, the roller plate is located directly above the guide roller, and the rollers inside the roller plate are rotatable.

[0008] According to another advantageous design of the present invention, a limiting groove is provided at the end of the roller plate near the electric push rod, the spring force of the trapezoidal frame is less than that of the roller plate spring, and the inclined surface of the trapezoidal frame is located inside the limiting groove of the roller plate. The top of the vertical plate moves through the top of the U-shaped plate, and the telescopic end of the U-shaped telescopic plate is located on the movement trajectory of the top of the vertical plate. The U-shaped telescopic plate is elastically designed, so that the trapezoidal frame can apply different magnitudes of thrust according to the thickness of the thin plate. When the U-shaped plate moves horizontally, it drives the roller plate to move synchronously, and the roller plate drives the vertical plate to move. The top of the vertical plate abuts against the arc surface of the telescopic end of the U-shaped telescopic plate. At this time, the telescopic end of the U-shaped telescopic plate contracts, and the spring force applies downward pressure to the vertical plate, and the vertical plate applies downward pressure to the roller plate.

[0009] According to another advantageous design of the present invention, the anti-dent device includes a mesh plate disposed inside and above the base. Two telescopic inclined plates are symmetrically and hinged to the bottom of the mesh plate by torsion springs. A U-shaped plate drives a bending plate to move towards the center of the base. The bending plate drives a connecting plate to move synchronously. The connecting plate drives the telescopic inclined plates to move synchronously. The telescopic end of the telescopic inclined plate is limited by the mesh plate. A connecting plate is hinged to the bottom side wall of the telescopic inclined plate. A bending plate is slidably mounted through the connecting plate at the end away from the telescopic inclined plate.

[0010] According to another advantageous design of the present invention, the top of the mesh plate is flush with the bottom of the inner wall of the U-shaped plate, the telescopic inclined plate is elastically designed, the top of the bending plate is fixedly installed at the bottom of the U-shaped plate, at which time its hinge shaft begins to rotate, the telescopic inclined plate moves in an arc trajectory and pushes the mesh plate upward, the top of the mesh plate fits against the bottom of the thin plate and forms a support, ensuring that the thin plate as a whole always maintains a flat state.

[0011] According to another advantageous design of the present invention, two fixed frames are symmetrically and fixedly installed on the bottom of the inner wall of the base. Two rows of toothed blocks are symmetrically and fixedly installed inside each fixed frame, and the two rows of toothed blocks are circumferentially distributed inside the fixed frame. A gear is rotatably mounted on the central plane of the bending plate. During movement, the gear meshes with the toothed blocks. When the bending plate moves towards the cutting mechanism following the U-shaped plate, the bending plate drives the gear to move synchronously. During the movement of the gear, it meshes with the circumferentially distributed toothed blocks at both ends inside the fixed frame, causing the gear to generate positive... The gear has a lead screw that is fixedly installed inside it. The connecting plate is installed near the gear and movably mounted on the outer wall of the lead screw. The outer wall of the lead screw has a non-self-locking spiral groove. The gear drives the lead screw to move synchronously. When the lead screw rotates forward, it guides the internal locking block of the connecting plate through the non-self-locking spiral groove on its outer wall, causing the connecting plate to slide downward along the inside of the bending plate. When it rotates in reverse, the connecting plate resets. That is, the connecting plate causes the mesh plate to move downward when the thin plate is cut, so as to get rid of the resistance to the thin plate. After the cutting is completed, it supports the bottom of the thin plate.

[0012] According to another advantageous design of the present invention, the anti-adhesion device includes an arc-shaped frame, the bottom of which is fixedly installed on the bottom of the inner wall of the base. Two bearing frames are symmetrically and fixedly installed on the outer sidewall of the bent plate. A movable plate is vertically and slidably installed inside the bearing frame via a spring. The bent plate drives the bearing frame to move, and the bearing frame drives the movable plate to move synchronously. The arc surface of the movable plate contacts the arc-shaped frame, causing the movable plate to generate an upward force. An air jet mechanism is provided in the hollow part of the movable plate.

[0013] According to another advantageous design of the invention, the arc surface of the arc frame is located on the movement trajectory of the movable plate, and the interior of the movable plate is hollow. The gas ejected by the jet mechanism is the protective gas required for laser cutting. The movable plate slides upward along the interior of the support frame. The movable plate drives the jet mechanism to move synchronously. During the process of the mesh plate releasing its support for the thin plate, the jet mechanism approaches and ejects protective gas to the bottom of the thin plate, thereby applying an upward thrust to the thin plate during the cutting process in a pneumatic manner.

[0014] According to another advantageous design of the present invention, a baffle is slidably mounted on the outer sidewall of the support frame by a spring, and an inclined block is fixedly mounted on the top of the inner wall of the support frame. A sealing plate is hinged to the top edge of the movable plate by a torsion spring. When the movable plate rises, it abuts against and pushes the bottom of the baffle, and the baffle slides upward along the outer sidewall of the support frame. At this time, the baffle blocks the cutting area, and the movable plate drives the sealing plate to move synchronously. The inclined surface of the inclined block is located on the top movement trajectory of the sealing plate. During the rising process, the sealing plate contacts the inclined surface of the inclined block. Under the guidance of the inclined block, the hinge shaft of the sealing plate begins to rotate, and the sealing plate swings towards the center of the movable plate. At this time, the sealing plate reduces the flow space of the gas ejected by the jet mechanism.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: by cooperating with an electric slide rail, a sliding plate, an electric push rod, a U-shaped plate, a guide roller, a roller plate, a trapezoidal frame, a vertical plate, and a U-shaped telescopic plate, the guide roller, which is rotated, prevents the thin plate from bending and breaking due to excessive friction when it enters the U-shaped plate. Furthermore, the U-shaped plate supports rather than clamps the ends of the thin plate, preventing bending deformation of its center due to contact force and preventing the laser cutting point from deviating from the predetermined position. Through the adaptive fitting and displacement of the roller plate, and the downward pressure applied by the U-shaped telescopic plate, combined with the guide roller, the stability of the thin plate's edge during the cutting process is ensured. Simultaneously, the edge remains flat during insertion and removal, preventing creases caused by frictional blockage. Moreover, the trapezoidal frame applies different amounts of thrust according to the thickness of the thin plate, completing the plate's orientation correction while preventing the edge of the thin plate from bending due to excessive thrust.

[0016] By incorporating an anti-dent device, a combination of a U-shaped plate, a mesh plate, a telescopic inclined plate, a connecting plate, a bending plate, a fixed frame, toothed blocks, gears, and a lead screw, the mesh plate's support mitigates the downward force generated at the center of the thin plate due to its excessive width. This prevents the plate from bending and sagging at its center, thus avoiding changes in the predetermined laser cutting point and ensuring cutting accuracy. The lead screw's drive prevents the mesh plate from bending and deforming at the center of the thin plate due to sagging. Furthermore, the mesh plate's close contact with the plate during laser cutting prevents debris from adhering to the cut edges due to high temperatures, thus contaminating the raw material and reducing cutting quality.

[0017] By incorporating an anti-adhesion device, a combination of a bending plate, curved frame, load-bearing frame, movable plate, air jet mechanism, baffle, inclined block, and sealing plate, the air jet mechanism moves upward to apply sufficient pneumatic thrust to the thin plate. This further prevents the thin plate from sagging due to loss of support during cutting. Simultaneously, sufficient space is reserved between the thin plate and the mesh plate. Under the blowing of the air jet mechanism, the cutting debris is thoroughly cooled, preventing hot debris from adhering to the surface of the thin plate again. The baffle reduces the influence of external light sources on the laser beam of the cutting mechanism, while the sealing plate reduces the flow space of the protective gas, further ensuring pneumatic support for the bottom of the thin plate and optimizing the support effect during cutting.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-8 As shown, one embodiment of the present invention provides: a five-axis CNC machine tool with equidistant cutting function, comprising: a base 1, two support mechanisms 2 symmetrically arranged around the base 1, a sliding mechanism 3 arranged on the top of the support mechanism 2, a drive mechanism 4 slidably mounted on the left side of the sliding mechanism 3, a cutting mechanism 5 arranged at the bottom of the output end of the drive mechanism 4, two electric slide rails 6 symmetrically and fixedly mounted on the outer sidewall of the base 1, a sliding plate 7 slidably mounted inside the electric slide rail 6, an electric push rod 8 fixedly mounted on the side of the sliding plate 7 away from the base 1, and the electric push rod 8 is telescopic, a U-shaped plate 9 fixedly mounted on the telescopic end of the electric push rod 8, an anti-denting device 15 for supporting the thin plate is arranged below the U-shaped plate 9, and the anti-denting device 15 is surrounded by... An anti-adhesion device 16 is provided to prevent cutting debris from adhering. Several guide rollers 10 are equidistantly and rotatably installed inside the square groove of the U-shaped plate 9. Roller plates 11 are slidably installed on the inner side wall of the U-shaped plate 9 via springs. A trapezoidal frame 12 is slidably installed on the bottom of the inner wall of the U-shaped plate 9 via springs. A vertical plate 13 is fixedly installed on the top of the roller plate 11. A U-shaped telescopic plate 14 is fixedly installed on the top of the sliding plate 7. By rotating the guide rollers 10, the thin plate is prevented from bending and breaking due to excessive friction when it enters the U-shaped plate 9. The U-shaped plate 9 supports rather than clamps the two ends of the thin plate to avoid bending deformation of its center position due to the force of resistance, and to prevent the laser cutting point from deviating from the predetermined position.

[0022] The drive mechanism 4 is a multi-axis drive device, the cutting mechanism 5 is a laser cutter, the telescopic end of the electric push rod 8 moves through the interior of the sliding plate 7, the bottom of the U-shaped plate 9 has a square groove, the roller plate 11 is located directly above the guide roller 10, and the rollers inside the roller plate 11 are rotatable.

[0023] A limiting groove is provided at one end of the roller plate 11 near the electric push rod 8. The spring force of the trapezoidal frame 12 is less than that of the spring force of the roller plate 11, and the inclined surface of the trapezoidal frame 12 is located inside the limiting groove of the roller plate 11. The top of the vertical plate 13 moves through the top of the U-shaped plate 9. The telescopic end of the U-shaped telescopic plate 14 is located on the top movement trajectory of the vertical plate 13, and the U-shaped telescopic plate 14 is designed to be elastic.

[0024] Through the adaptive fitting and displacement of the roller plate 11, and the downward pressure applied by the U-shaped telescopic plate 14, combined with the guide roller 10, the stability of the edge of the thin plate during the cutting process is ensured. At the same time, the edge of the thin plate is kept flat during insertion and removal to avoid creases caused by friction. The trapezoidal frame 12 applies different sizes of thrust according to the thickness of the thin plate to complete the orientation correction of the thin plate while avoiding the edge of the thin plate from bending due to excessive thrust.

[0025] During use, as the thin sheet material is horizontally placed into the U-shaped plate 9 from left to right, the bottom of the thin sheet contacts the circumferential surface of the guide roller 10 inside the bottom end of the U-shaped plate 9. The thin sheet causes the guide roller 10 to rotate due to friction, thereby converting the sliding friction between the thin sheet and the U-shaped plate 9 into rolling friction. Then, the electric push rod 8, which is limited by the sliding plate 7, is activated. The telescopic end of the electric push rod 8 pushes the U-shaped plate 9 towards the center of the base 1. At this time, the U-shaped plate 9 increases the bearing area of ​​the thin sheet. Then, the electric slide rail 6 is activated, and the electric slide rail 6 drives the sliding plate 7 towards the cutting mechanism 5. The thin sheet moves synchronously. When the cutting mechanism 5 performs laser cutting on the thin sheet, the drive mechanism 4 and the sliding mechanism 3 operate synchronously, enabling multi-axis motion. The drive mechanism 4 and the electric slide rail 6 achieve equidistant displacement and cutting of the thin sheet. Thin sheets of different thicknesses contact the circumferential surface of the guide roller 10. At the same time, its top will contact and push the circumferential surface of the roller inside the roller plate 11, causing the roller plate 11 to slide upward along the inner side wall of the U-shaped plate 9. At this time, the roller plate 11 adapts to the top edge of the thin plate of different thicknesses, and when the roller plate 11 rises, it releases the restriction on the inclined surface of the trapezoidal frame 12. The trapezoidal frame 12 abuts against the side wall of the thin plate through the spring force. The thicker the thin plate, the more the roller plate 11 rises, and the greater the displacement force of the trapezoidal frame 12, and vice versa. Thus, the trapezoidal frame 12 can apply different magnitudes of thrust according to the thin plate of different thicknesses. When the U-shaped plate 9 moves horizontally, it drives the roller plate 11 to move synchronously. The roller plate 11 drives the vertical plate 13 to move. The top of the vertical plate 13 abuts against the arc surface of the telescopic end of the U-shaped telescopic plate 14. At this time, the telescopic end of the U-shaped telescopic plate 14 contracts, and the vertical plate 13 applies downward pressure to the vertical plate 13 by relying on the spring force. The vertical plate 13 applies downward pressure to the roller plate 11.

[0026] According to the above embodiment, by rotating the guide roller 10, the thin plate is prevented from bending and breaking due to excessive friction when it enters the U-shaped plate 9. The U-shaped plate 9 supports rather than clamps the two ends of the thin plate, avoiding bending deformation of its center position due to the contact force, and preventing the laser cutting point from deviating from the predetermined position. Through the adaptive fitting and displacement of the roller plate 11 and the downward pressure applied by the U-shaped telescopic plate 14, combined with the guide roller 10, the stability of the edge of the thin plate is ensured during the cutting process. At the same time, the edge of the thin plate is kept flat during insertion and removal, avoiding creases caused by friction. The trapezoidal frame 12 applies different amounts of thrust according to the thickness of the thin plate, completing the orientation correction of the thin plate while preventing the edge of the thin plate from bending due to excessive thrust.

[0027] like Figures 1-8 As shown, based on the above embodiment: anti-dent device 15.

[0028] The anti-dent device 15 includes a mesh plate 151, which is located inside the base 1. The bottom of the mesh plate 151 is symmetrically connected to two telescopic inclined plates 152 by torsion springs. A connecting plate 153 is hinged to the bottom side wall of the telescopic inclined plate 152. A bending plate 154 is slidably installed on the end of the connecting plate 153 away from the telescopic inclined plate 152.

[0029] The top of the mesh plate 151 is flush with the bottom of the inner wall of the U-shaped plate 9, the telescopic inclined plate 152 is elastically designed, and the top of the bending plate 154 is fixedly installed at the bottom of the U-shaped plate 9.

[0030] Two fixed frames 155 are symmetrically and fixedly installed on the bottom of the inner wall of the base 1. Two rows of toothed blocks 156 are symmetrically and fixedly installed inside the fixed frames 155. The two rows of toothed blocks 156 are circumferentially distributed inside the fixed frames 155. A gear 157 is rotatably installed on the middle plane of the bending plate 154. The gear 157 meshes with the toothed blocks 156 during the movement. A lead screw 158 is fixedly installed through the gear 157. A connecting plate 153 is movably installed on the outer wall of the lead screw 158 near the end of the gear 157. The outer wall of the lead screw 158 is a non-self-locking spiral groove.

[0031] The support of the stencil 151 mitigates the downward force caused by the excessive width of the thin plate at its center, preventing it from bending and sagging, which would alter the predetermined landing point of the laser cutting and prevent changes in the equidistant cutting distance, thus ensuring cutting accuracy. The drive of the lead screw 158 ensures that the stencil 151 does not bend or deform due to sagging at the center of the thin plate, while also preventing the debris generated during laser cutting from re-adhering to the cut edge due to high temperature, thus contaminating the raw material and reducing cutting quality.

[0032] In use, the U-shaped plate 9 drives the bending plate 154 to move closer to the center of the base 1. The bending plate 154 drives the connecting plate 153 to move synchronously, and the connecting plate 153 drives the telescopic inclined plate 152 to move synchronously. The telescopic end of the telescopic inclined plate 152 is limited by the mesh plate 151. At this time, its hinge shaft begins to rotate, and the telescopic inclined plate 152 moves in an arc trajectory and pushes the mesh plate 151 upward. The top of the mesh plate 151 is attached to the bottom of the thin plate and forms a support, ensuring that the thin plate always remains flat. When the bending plate 154 moves with the U-shaped plate 9 closer to the cutting mechanism 5, the bending plate 154 drives the gear 157. In synchronous motion, the gear 157 meshes with the toothed blocks 156 distributed circumferentially at both ends inside the fixed frame 155, causing the gear 157 to generate forward and reverse rotation forces. The gear 157 drives the lead screw 158 to move synchronously. When the lead screw 158 rotates forward, it guides the internal locking block of the connecting plate 153 through the non-self-locking spiral groove on its outer wall, causing the connecting plate 153 to slide downward along the inside of the bending plate 154. When it rotates in reverse, the connecting plate 153 resets. That is, the connecting plate 153 causes the mesh plate 151 to move downward when the thin plate is cut, detaching from the resistance to the thin plate. After the cutting is completed, it supports the bottom of the thin plate.

[0033] According to the above embodiment, the support of the stencil 151 mitigates the downward force generated at the center of the thin plate due to its excessive width, preventing it from bending and falling at its center, thus changing the predetermined landing point of the laser cutting and preventing changes in the equidistant cutting distance, thereby fully ensuring cutting accuracy. The drive of the lead screw 158 ensures that the center of the thin plate does not bend or deform due to falling, while also preventing the debris generated during laser cutting from adhering to the cut edge of the thin plate again due to high temperature, thus contaminating the raw material and reducing the cutting quality.

[0034] like Figures 1-8 As shown, based on the above embodiment: anti-adhesion device 16.

[0035] The anti-adhesion device 16 includes an arc frame 161. The bottom of the arc frame 161 is fixedly installed on the bottom of the inner wall of the base 1. Two bearing frames 162 are symmetrically and fixedly installed on the outer side wall of the bending plate 154. A movable plate 163 is vertically and slidably installed inside the bearing frame 162 by means of a spring. An air jet mechanism 164 is provided in the hollow part of the movable plate 163.

[0036] The curved surface of the curved frame 161 is located on the movement trajectory of the movable plate 163, and the interior of the movable plate 163 is hollow. The gas ejected by the jet mechanism 164 is the protective gas required during laser cutting.

[0037] A baffle 165 is slidably installed on the outer side wall of the bearing frame 162 via a spring. An inclined block 166 is fixedly installed on the top of the inner wall of the bearing frame 162. A sealing plate 167 is hinged to the top edge of the movable plate 163 via a torsion spring. The inclined surface of the inclined block 166 is located on the top movement trajectory of the sealing plate 167.

[0038] By moving the jet mechanism 164 upward, sufficient pneumatic thrust is applied to the thin plate, further preventing the thin plate from falling due to loss of support during the cutting process. At the same time, sufficient space is reserved between the thin plate and the mesh plate 151. Under the blowing of the jet mechanism 164, the cutting debris is fully cooled, preventing the hot debris from adhering to the surface of the thin plate again. The baffle 165 reduces the influence of external light sources on the laser beam of the cutting mechanism 5. At the same time, the sealing plate 167 reduces the flow space of the protective gas, further ensuring the pneumatic support of the bottom of the thin plate and optimizing the support effect during cutting.

[0039] In use, the bending plate 154 drives the support frame 162 to move, and the support frame 162 drives the movable plate 163 to move synchronously. The curved surface of the movable plate 163 contacts the curved frame 161, causing the movable plate 163 to generate an upward force. The movable plate 163 slides upward along the inside of the support frame 162. The movable plate 163 drives the jet mechanism 164 to move synchronously. During the process of the mesh plate 151 releasing its support for the thin plate, the jet mechanism 164 approaches and sprays protective gas onto the bottom of the thin plate, thereby applying an upward thrust to the thin plate during the cutting process pneumatically. When the movable plate 163 rises, it abuts against and pushes the bottom of the baffle 165. The baffle 165 slides upward along the outer side wall of the support frame 162. At this time, the baffle 165 blocks the cutting area. At the same time, the movable plate 163 drives the sealing plate 167 to move synchronously. During the rise of the sealing plate 167, it contacts the inclined surface of the inclined block 166. Under the guidance of the inclined block 166, the hinge shaft of the sealing plate 167 begins to rotate. The sealing plate 167 swings towards the center of the movable plate 163. At this time, the sealing plate 167 reduces the flow space of the gas ejected by the jet mechanism 164.

[0040] According to the above embodiment, by moving the jet mechanism 164 upward, sufficient pneumatic thrust is applied to the thin plate, further preventing the thin plate from falling due to loss of support during the cutting process. At the same time, sufficient space is reserved between the thin plate and the mesh plate 151. Under the blowing of the jet mechanism 164, the cutting debris is sufficiently cooled, avoiding the hot debris from adhering to the surface of the thin plate again. By blocking the baffle 165, the influence of external light sources on the laser beam of the cutting mechanism 5 is reduced. At the same time, the sealing plate 167 reduces the flow space of the protective gas, further ensuring the pneumatic support for the bottom of the thin plate and optimizing the support effect during cutting.

[0041] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
